Answer:
When young children go on a picnic without any adult I see this as a nightmare scenario.
Explanation:
School age is really young and vulnerable. This is age when human development takes place. When school boys are left unattended they can indulge in immoral activities. When schoolboys marooned on an island without any adult supervising them they can have opportunity to do whatever they can. They can fight with each other, harm each other or involve in immoral activities with one another or together. This is nightmare for any parent.
